简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 =-e`OHA qQu}4Ye> 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: {T^"`%[ enableservice('AutomationServer', true) .m]"lH* enableservice('AutomationServer') Az}.Z'LJ kIlc$:K^ 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 j<-#a^jb &]'{N69@d? 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: +;P8QZK6 1. 在FRED脚本编辑界面找到参考. ;p!|E3o. 2. 找到Matlab Automation Server Type Library +M"Fv9 3. 将名字改为MLAPP -r6cK,WVU ")t
